To all 'whom t may concern:

Be it known that I, OWEN S. CURrNEn, a citizen of the United States, residing at St. Paris, in the county of Champaign and State of Ohio, have invented a new and useful Improvement in Feed-Governors, of which the following is a specification.

This invention relates to a feed governor, or regulator for the purpose of controlling the flow of wheat to the feed rollers of a flouring mill, and the object of the invention is to maintain a regular constant flow, thereby preventing choking of the rollers and at the same time insuring a steady supply of wheat in exactly the right amount to enable the mill to be operated at its maximum of efliciency.

With these objects in view, the invention consists of a casing interposed between the rollers and the source of supply and through which the wheat is passed on the way to said rollers, and a scroll shaped pivoted gov* ernor arranged in said casing and adapted to swing back and forth automatically, and by said swinging movement to cover and uncover the inlet and discharge openings from said casing.

The invention also consists of the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which,

Figure l is a vertical section, the governor being shown in position for cutting off the supply of wheat to the rollers. Fig. 2 is a similar sectional view the governor being in position to permit the desired amount of wheat to pass through the casing to the rollers. Fig. 3 is a section on the line 3 3 of Fig. l.

In these drawings l represents a pipe or conduit leading from a source of supply, and 2 a feed pipe leading to the rolls, not shown. interposed bet-Ween pipes 1 and 2 is a metal casing 5 provided with suitable top and bottom flanges by means of which it may be readily secured in position and while the sides of said casing may vary in different mills the same is preferably about eight inches square. -It is not essential that the casing be exactly squaren cross section as any rectangular shape found convenient may be employed. Extending transversely through said casing and about midway its ends is a rock shaft 4t. Arranged within the casing and fixed upon said shaft is a Specification of Letters Patent.

sheet metal governor 8 bent in the shape of a scroll or the letter S and of such width that it will extend from one side of the casing to the other. Fixed upon one outer end portion of the shaft 4 is a scale beam 6 provided wit-h a slidable weight 7. Fixed to the opposite extending portion of the rock shaft is an arm 8 which extends in a direction opposite to that of the beam 6 and a spring 9 has one end fixed to any suitable stationary support and the other end is secured to the arm 8, and said spring acts as a yielding check upon the weighted beam 6, thereby insuring gradual opening and closing movement of the governor 3 as distinguished from a rapid or jerking movement which would be the case if the weight alone was depended upon for regulating such movement.

In the upper portion of the casing and in communication with the pipe l is a small feed hopper 10, the lower discharge end of which is concaved so as to have a curvature to that of the upper end of the governor. The lower portion of the governor is adapte-d to engage the front side of the casing, and while in engagement with said front side cuts off flow of wheat through the casing into a receiving hopper 1l located in the lower portion of the casing and discharging into the pipe 2.

lt will be obvious that with the parts in the position shown in Fig. l wheat will pass into the upper front portion of the casing, it being understood that no grain at any time can get to the rear of the scroll governor 3, and when a certain amount of wheat has accumulated in the casing the weight of the same will cause the governor to tip, and the lower portion will swing away from the front of the casing, and permit the grain to flow to the pipe 2.

It will be noted that the governor is so shaped and mounted that as the lower portion moves away from the casing front the upper portion will travel across the concaved bottom of the hopper l0, the extent of such movement being exactly equal to the movement away from the casing front of the lower port-ion. Consequently the amount of wheat fed from the lower portion of the casing into the pipe 2 will always be in proportion to the amount permitted to flow into the upper portion of the casing from the hopper l0 and the governor will always so adjust itself as to maintain a perfect balance between the two portions of the casing, thereby maintaining a steady and continuous flow of wheat to the rolls. if at any time the fiow of wheat through the pipe 2 should be checked thereby tending to cause an undue accumulation of wheat in the casing the governor 3 will be swung so far from the front of the casing by the weight of the grain bearing upon it that he discharge from the hopper l0 will be entirely outoff until the rate of fiow through the pipe 2 has been restored to its normal condition. At the same time should there be any checking of the flow of grain to the rolls from a point above the casing the scroll ygovernor will swing in the opposite direction and open the hopper l0 to its full width and as Soon as the normal fiow is re-established it will automatically readjust itself to continue the How at the normal rate. By means of the weight 7 adjustment can be made so that the feed of grain through the casing can be maintained in the amount desired.

What I claim is:-

l. A feed governor for flour mills coinprising a casing having a grain receiving inlet at its upper end and a grain discharge opening at its lower end, and a balanced scroll shaped governor mounted in said casing, said governor being normally clear of the upper inlet and rocked by weight of the grain flowing upon it to close said inlet when a predetermined quantity of grain has been deposited on the governor.

2. in a governor for iiour mills a casing having an inlet opening, a scroll shaped governor mounted therein, an adjustable Weight operatively connected to said governor7 the lower portion of the governor being adapted to engage the front of the casing7 and the upper end of the governor being adapted to work across said inlet opening in the upper portion of the casing, said governor normally resting clear of the inlet opening.

3. A feed governor for mills comprising a casing having a hopper arranged in its upper portion, said hopper having a concaved lower end, a receiving hopper arranged in the bottom of the casing and adapted to discharge grain from said casing, and an S-shaped governor pivotally mounted within the casing, said governor having a width equal to that of the interior of the casi-ng, the upper end of the Igovernor working across the conoaved bottom of the first mentioned hopper and the lower portion of the governor being adapted to engage the front of the casing above the second mentioned hopper.

Li. A device of the kind described comnising a Casing having a grain inlet at the upper end and discharging grain from the lower end, a rock shaft extending transversely through the casing, a scroll shaped governor mounted on said shaft7 the upper portion of the governor working across the grain inlet and normally having its upper portion clear of said inlet, and the lower portion cooperating with a side of the casing for the purpose of cutting oif communication between the upper and lower portions of the casing, a beam fixed upon a project ing end of the shaft, an adjustable weight on said beam, an arm carried bv the shaft, and extending in a direction opposite to that of the said beam, and a spring having one end fixed and the other end secured to said arm, as and for the purpose set forth.
